Can you give more detail on the actual application of said Mic? The reason I ask is that there are loads of microphones, each with a slightly differing purpose.
How many subjects does it need to record? Distance from the mic to the person? Noise level of the room (computers, furnace, is the room empty, has lots of furniture)? How is it being recorded (portable recorder? Computer?)? etc.
For example, an omni-directional condenser might just be the right choice, but it may be better to go cheaper on the mic and spend the balance on treating the room with audio foam to dump the echo a bit. Or if you don't give two s***s about the mic being seen in the frame, a Shure SM58 Dynamic Mic being held by the speaker "interview style" will do the job just fine. Or even further to that, lapel mics might be the right choice but will limit the movement of the user.
